CD-133.2 No Embossing - MLOD - Glass Button Under Dome - Crude Blue Aqua - Measured 75 mm Wide x 105 mm Tall. It was interesting to note that there was a 12 mm high (3/8 ") cavity above the insulator threads. To me, this looked like a typical American Insulator / Oakman cavity above the threads.

The following picture shows the glass button and internal threading of this CD 133.2 No Embossing insulator.
